No Indictment for Officer Darren Wilson in Fatal Shooting of Michael Brown in Ferguson

After months of deliberation, a grand jury has decided not to indict police officer Darren Wilson in the fatal Aug. 9 shooting of 18-year-old Michael Brown in Ferguson, Missouri.

Wilson faced various criminal charges, including first-degree murder and involuntary manslaughter. The grand jury determined there was not enough evidence to indict Wilson on any of the charges, St. Louis County Prosecuting Attorney Bob McCulloch announced Monday night.

A grand jury of nine whites and three blacks had been meeting weekly since Aug. 20 to consider evidence. At least nine votes would have been required to indict Wilson.

Wilson claimed he shot and killed Brown after a physical altercation that spilled into his police cruiser. He also alleged Brown went for his firearm.

The fatal shooting sparked unrelenting protests — several of which turned violent — in Ferguson. Law enforcement officials have been preparing for further unrest now that the grand jury decision has been announced. Missouri Gov. Jay Nixon also summoned the National Guard.

In a statement, the family of Michael Brown said they are "profoundly disappointed" in the decision.
